What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are 0.25mm larger in diameter than standard bearings. This is necessary when the crankshaft journals have been machined undersize during an engine rebuild to remove wear or damage.

What is the pMax Black material?

pMax Black is King Engine Bearings' racing line material. It's a tri-metal construction designed for higher load capacity and improved durability compared to standard bearings, making it suitable for performance-oriented engine builds.

Do these bearings come with installation hardware?

This product is a main bearing set only. Installation hardware, such as main bearing bolts, is typically sold separately and should be replaced according to the manufacturer's service manual.

About this part

Product Details

These King Engine Bearings main bearings are built with a pMax Black tri-metal material, a design choice that offers improved load capacity for performance applications. They are specifically sized at +0.25mm, meaning they are 0.25mm larger than standard, which is crucial when the crankshaft journals have been machined down during an engine rebuild. This set is designed for a range of Audi and Volkswagen engines, including those found in models like the Audi 80, Audi 90, and Volkswagen EuroVan.

The pMax Black material is a step up from standard bearings, offering enhanced durability and performance characteristics that can handle more demanding engine conditions. When you're rebuilding an engine and need to ensure the main bearings are precisely sized for the crankshaft, a set like this provides the confidence you need. They fit right into the specified Audi and VW applications, making them a solid option for engine overhauls where precision is key.
